2 Process until finely chopped; gradually pour in olive oil and process until all ingredients are thoroughly combined.

3 For chicken marinade, combine all marinade ingredients (using 1/4 cup of the pesto you just made and reserving remaining pesto for later use). Place marinade and chicken in a bowl or zip-top plastic bag. Make sure chicken is thoroughly covered; refrigerate 6-8 hours.

7 In same skillet that you cooked the chicken in, saute mushrooms and sun-dried tomatoes in remaining 2 tablespoons oil and 1 tablespoon white wine until mushrooms are tender and liquid is absorbed; divide into 6 equal portions; set aside.

8 Separate thinly sliced Gouda into 6 equal portions.

9 Cut 12 slices, 1/2″ thick, from Italian bread loaf.

10 For each sandwich, do the following:.

11 Take two slices of bread; spread 1 tablespoon pesto on each slice.

12 On one slice of bread, layer chicken strips, mushroon/tomato mixture, and then Gouda slices.

13 Place remaining bread slice, pesto side down on top of cheese.

14 Spread approximately 1 teaspoon butter on top bread slice.

15 Place, buttered side down, on preheated griddle or grill.

16 With a spatula, press down on the sandwich – just to kind of “smoosh” it together, and while it is cooking, spread approximately 1 teaspoon butter on top slice of bread. Grill approximately 5 minutes, flip and grill approximately 3-5 minutes more or until cheese is melted and bread is golden brown and crispy.

17 Repeat for remaining sandwiches.

18 ***Lighter version***.

19 For pesto sauce, substitute 1/2 cup chicken or vegetable broth for the olive oil and omit the salt (if using low-sodium chicken or vegetable broth, you may not want to omit the salt) and reduce pine nuts to 1/3 cup or omit altogether (if you want to go even lighter).

22 Omit the butter that is spread on top of the bread before grilling and instead use a lighter spread – I use Smart Balance Light Buttery Spread w/ Flax, or I Can't Believe It's Not Butter Spray (No fat or calories in this one).

23 Depending on which and how many of the suggested changes you make, you could cut the fat and calories significantly and still have a tasty panini. :).
